I dont think there is a designated plug. And I dont think there is a way to cleanly drain a little coolant. When I changed my water pump, what I discovered was that undoing any of the clamped joint marked in below picture results in a gushing coolant stream flowing out.Is there a coolant drain plug on these 987 M97 engines like there is on 986 M96s?
For various reasons, I'd like to be able to drain a little coolant out and inspect it.
If no plug, how do I go about that? Thanks.
